ember skyfire diamond

New mage user here. Love the program, still figuring out how to tweak things correctly. Was hoping someone could confirm, looks to me that the ember skyfire diamond is giving +2 int, instead of +2%. thanks!

ok on my toon ive got the 12 spell dam + run speed meta in the destruction holo goggles and its calling that 71.79 dps
if i swap out that meta for the ember skyfire it ups it to 74.19 dps...i dont doubt im missing something, but im not seeing it

also with the first gem rawr shows me 654 int, with the ember skyfire it displays 657

Do you perhaps have a different gem in the other gem slot on those 2 helms? Or you don't have the gem colors required to meet one/both of the metas? Try looking at the chart for just metas. When I equip the ember metagem with no other changes, it goes
from 902int to 920int (902 * 1.02 = 920.04), so looks correct here.
